Liberal democracy index during each head of government's tenure

Every head of government since 1991, ranked by how the liberal democracy index changed from their first day in office. Politare shows what happened during a tenure; it does not claim the office-holder caused it.

Sorted by total, highest first. Every row is indexed to the last count complete before the first day in office ("from" marks a start that had to move because that count had no data, or because the period cut it); Levels are per cent changes, rates are differences in points; "per year" compounds levels and divides rates.
